找不到类型为“object”的不同支持对象“[object]”。-->要在表中显示的VirusTotal JSON

virus-scanning angular8 .net-core typescript angular

techno · 技术社区 · 5 年前

我正在尝试解析virustotaljson中的数据,以便在桌子。但是我不能用 ngfor公司

 scan(file) {

    this.http.get("api/Scanner/").subscribe(result => {
    this.value = result;
    console.log(this.value.scans);    
    });

    }

<li *ngFor="let item of this.value.scans">
  {{item.version}}
</li>

   public class ScannerController : Controller
        {   [HttpGet]         
            public async Task<IActionResult> ScanAsync(string file_id)
            {
                //New Update //
                file_id = "./wwwroot/Upload/1";
                VirusTotal virusTotal = new VirusTotal("mykey");
                // virusTotal.UseTLS = true;         
                FileStream stream = System.IO.File.OpenRead(file_id);
                byte[] fileBytes = new byte[stream.Length];
               // stream.Seek(0, SeekOrigin.Begin);
                stream.Read(fileBytes, 0, fileBytes.Length);

                VirusTotalNet.Results.FileReport report = await virusTotal.GetFileReportAsync(fileBytes);
                bool hasFileBeenScannedBefore = report.ResponseCode == FileReportResponseCode.Present;

                Console.WriteLine("File has been scanned before: " + (hasFileBeenScannedBefore ? "Yes" : "No"));

                //If the file has been scanned before, the results are embedded inside the report.
                if (hasFileBeenScannedBefore)
                {
                   return Ok(report);
                }
                else
                {
                    ScanResult fileResult = await virusTotal.ScanFileAsync(fileBytes,"1");
                    return Ok(fileResult);

                }

            }
        }

this.value.scans 不是数组,但它是对象。我们把它转换成一个数组。

this.http.get("api/Scanner/").subscribe(result => {
    this.value = result;
    // this line will transform your object to an array
    this.value.scans = Object.keys(this.value.scans).map(key => {
        return {
            ...this.value.scans[key],
            scannerName: key
        };
    });

});
